Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82816, here are decompositions:

3 + 82813 = 82816
5 + 82811 = 82816
17 + 82799 = 82816
23 + 82793 = 82816
29 + 82787 = 82816
53 + 82763 = 82816
59 + 82757 = 82816
89 + 82727 = 82816

Showing the first eight; more decompositions exist.
